Definition

In functional electrical stimulation (FES), computer technology sends low-level electrical impulses to activate specific muscles in your legs, arms, hands or other areas. The electrical impulses are sent to the muscles either through surface electrodes on the skin or through electrodes implanted just under the skin. The electrical stimulation can cause your muscles to contract, which may promote increased muscle bulk or muscle control.

Functional electrical stimulation may improve your range of motion, your strength, and the functional use of your hands, arms or legs. FES may help you perform activities such as grasping or holding an item with your hand or moving your arms or legs in a cycle or stepping motion.

Functional electrical stimulation is normally used in combination with other therapy techniques, education and exercise programs. Your therapy goals may include improving how you perform your daily activities and creating a wellness program you can use at home.
